Specification of Letters Patent.

Application filed April 29, 1912. Serial No. 693,972.

To all/whom it may concern citizen of the United States, residing at I Chicago, in the county of Cook and State of Illinois, have invented certain new and useful IITLPIOYOIHBIN IS lD Fireproof Building Construction, of which'the following" s a specification. v I

My invention relates to fireproof building construction, and more particularly concerns improvements in means for securing and maintaining building walls and such members as door, window and supporting frames, in their proper relative position.

The primary object of my invention-1s to provide improved means for firmly and securely anchoring or fastening door frames or like members to the wall tiling or other material of which the wall is composed; which means will be simple and reliable and will effectively prevent bulging, warping or relative displacement of the wall and frame members.

A further object of my invention is to provide improved means of this character which may be cheaply and conveniently manufactured, and which will be adaptable to various formsof building construction and to various positions and disposition with respect to the Wall tiling and frame members, depending upon the particular requirements or conditions under which it is to be used.

lVith these and other new and useful objects in view, as will hereinafter appear, my invention consists in the construction, combination and arrangement of parts herein described and shown in the accompanying drawings. which illustrate one embodiment of my invention.

In the drawings: Figure 1 is view illustrating a portion of a fireproof Wall having a door opening and a frame surrounding it,

and illustrating one way of distributing my anchoring devices to secure the best results.

Fig. 2 is a plan sectional view takentransversely of a portion of the wall and door frame substantially on the line 2-2 of Fig. 1. Fig. 3 is a sectional view on line 3-3 of Fig. 2. Fig. 4 is a View similar to Fig. 2 of a thicker and heavier wall showing my invention adapted to fastening oi corner piece members. Fig. 5 is a view in side elevation illustrating the corner piece retaining or fastening device, and Fig! 6 is a detail tragmentary' view more clearly showing the manner of attaching the retaining or anchoring device to the frame.

The wall and door frame construction illustrated in the drawing is intended as representative of any standard of desired fireproof building construction, and serves to exemplify my invention; but it will be obvious to one skilled in the art having obtained an understanding of my invention from the disclosures herein made, that my invention may be equally as well embodied. in modified structures more particularly adapted to other types of fireproof construction than that shown in the invention. The

wall A illustrated in the drawing has an opening or aperture Bfor the purpose of providing a door in the wall. The wall A is shown as composed of hollow fire-proof tile-bricks C, such as are extensively used in the construction of fire-proof buildings.

These tile-bricks are laid edgewise one above the. other in break-joint fashion in accord ance with the usual buildingmethods, and

are of the rectangular type, each brick having a number of interior cells D separated by partitions E. The edge of the door opening B is surrounded by a frame G for a door F.

The frame G shown in Figs. 1 to 3 inclusive, may be made of any suitable material, but is preferably of iron, so as to be fireproof, the material being of suiiicient thickness or strength for that purpose. This frame is hollow,so to speak, and .is consider.- ably thicker or Wider than the tile-bricli wall, so that the wall may'set into or interfitted in the door frame as shown. Aswill be seen, the sides orfaces H of the frame are spaced from adjacent faces J of the tile wall, in order to lie flush with the outer face, or surface K of the usual layer or layers L of plaster applied to the tile-brick wall. The plaster is also filled in between the frame and edge of the wall to make a solid structure. It will benoted that theedge J oi the frame is undercut or beveled inwardly to further insure against the loosening of the plaster.- The frame shown has a continuous shoulder or portion M forming a suitable space for the door F. p The structure shown. in Fig. 4 is slightly. diiierent ,in form and more particularly adapted to thicker and heavier walls. In such thicker walls it is generally unnecessary and less expensive to extend the door Patented not. is. rare.

frame over the entire edge of the wall, but 4 instead to extend it only part ay into the door opening and to provide round or angular corner piece or member ll the other side edge of the door opening. The intermediate space 0 may he filled in with plaster and made flush with the surface of the door frame and corner piece, although ob'vionsy this corner piece and frame may he formed in one piece if desired, or in any other suit-- able manner.

The frame G has a number of concealed longitudinal instanding ribs or ridges P, preferably formed integrally therewith, for

.the purpose of providing means to which the anchoring or retaining devices may he tened. Instead of ribs short lugs may he used, positioned at the points Where it is desired to anchor the fanie members, but the ribs serve the purpose to better advantage, for the reason that the anchoring. devices may be attached at any positions along the door frame and thus render the construc-' tion more adaptable to the Varying distances and slight inaccuracies which might occur in fitting the-bricks and frame.

In its simpler form the anchoring or re taining device is better shown in i, 5 and 6, as used for retaining the corner piece N, or any similar member, such as used for instance to protect a Wall edge. shown in these figures the device comprises a fiat relatively thin strap of meta ii'l'iiel. may hare one of its ends hent around to form an open hook @12 The hight in the loop or hoolr thus formed has an elongated slot R cut in it of a size and shape to admit the rib l of the door frame or corner piece, the case may he, whereby after the rib and bent portion Q; are interlitted the rib may be sWaged or riveted at S on the inside' of tee bend, as clearly shown in F igs. 5 and 6. Any other suitable manner of attaching the anchoring strap to the frame or'corner piece may he used if desired. The structure shown, however, has the advantage of elin'iiating" belts or other fastening devices passing through the exposed surface of the frame or corner piece. The metal strap may he as long as necessary to meet particular requirements. In the case of the corner piece or similar member (Fig. i) it may extend diagonally into the tile brick Wall, preferably in the plaster between the bricks.

The inner end portion of the strap has a slot or opening V into which a Wedging key U is inserted, as clearly shown. in Figs. and i l hen the device is used'tor door or Windgiv frames and the liheand the anchor strapiinay end straight into the Wall as shown in i. l. 2 and 3, I prefer to locate the key and hey slot in relative positions to the inns? partitions .l'l of the tile bricks, although, in the case of corner piece or like members as shown in Figs. iand 5, the i276"; may he positioned in the corners in the tile The disposition of these key memupon the particu arbricks. hers of course depen wall and frame member construction with which the anchoring devices are used.

i t Will. he seen that by forcing or driving}: the key between the partitions or walls of the bricks and the end of the key slot. as extremely powerful force may he applied along the strap Q, to draw the frame and Wall. firmly into relative position. in this manner the frame or other inei'nber and the tiles may he positively and permanently held together against Warping, bulging or rela tive displacement, and since the anchor in archers and lreys a re embedded in the Wall hy the plaster or other material 01": which the Wall may he composed, a solid compact structure may obtained. l urtherinoic it is to he noted that the anchoring devices are readily adaptable to various structures.

in the structure shown in Figs. 2 and 5; the anchoring; device preferably holtedto a. separate plate or member W haying several hooked or sent portions Q, instead of forming; these hooks in 'rally on the anchoring at p Q. This is of advantage Where the anchor straps are to he ""aclied to the frame at several points. (is orrangerocnt also has the advanta 'c that the parts are interchangeable, so that they may he carried separa in stock, and any length of strap :may he used. @therwise it "he parts Were made integral, it would. he ry to carry a complete device in stock every form of frame member used. rein an inspection of Fig. i it will be seen lat any number of these devices may he distributed. alifi'ig' the particu ar frame to he supported. In this latter vi W I have in cated the anchoring devices as positioned at the sides of the door. @hyiously, however, the dispositions and number of these devices to he used are determined by possibilit s of the structure being subjected. to overheat inc; by fire, r to othe warping; strains or conditions.

The shape and. dimensions of the par vs obviously must he designed in accordance with the particular requirements to he met. For instance, in the o1 heavy vault bank door frames the anchoring straps may be considerably lengthened and ext a sufficient distance into the Walls to ins. a solid, substantial structure.

i What I claim as new is l. in a construction of the class described, the coinhination of a fireproof Wall, a frame having a series of concealed ribs, and a. do vice consisting of a member rireted to said ribs and extending into wall, and ten- 1 sion exerting mechanism for adjustahly keying .aid device in said Wall to anchor said and trance firmly in relative position.

2. a construction. of the class descr i I n of a fireproof Wall, a. it

mergers lic door or like frame, having concealed instanding ribs, a flat metallic plate having J fireproof tile brick, of a metallic door frame having-integral concealed ribs, a fiat metallic plate concealed in said wall having slotted hooked portions into the slots of which said ribs project and are swaged to interlock said plate and door frame, a metal strap extension of considerable length bolted to said metal plate and embedded in said Wall, a slot adjacent the end of said strap metal extension, and a metallic key passing through said slot in wedging engagement with the Walls of adjacent tile bricks for drawing and anchoring said frame into position with respect to said wall.

4. In a construction of the class described, the combination with a wallcomposed of fire proof material, of a metallic door frame of U-shaped section having ribs on the three interior walls of the U-frame, a flat metallic plate within said frame having slotted hooked portions into the slots of which said ribs project and are swaged to interlock said plate and door frame, an anchoring device secured to said plate, and means for exerting tension on said anchoring device to hold said plate firmly against said well. i

5. In fire proof building constructions, the

combination with a wall composed of fire proof tile brick, a metallic door frame of U- shaped section, integral ribs on the threeinterior walls of said frame, a metallic plate within said frame and having slotted hooked portions into the slots of which saidribs project and are swaged to interlock said plate and door frame, a metal strap exten} sion secured'to said plate and embedded in said Well, a slot adjacent the end of .said' strap, and a metallic key passing through, said slot in Wedging engagement with the walls of adj acenttile bricks for drawing and anchoring said frame into positionwith respect to said Wall.

Indestimonj whereof I have signed my name to this specification, in the'presenceof two subscribing witnesses, on thisifitli day of April A. D. 1912- JACOB Gr. BRAUN.
